Supra Life halogen xenon bulbs use a rigid quartz capsule for durability that ensures precise beam control through solid state design, while providing up to 30% energy savings compared to standard halogens. A unique dichroic silvered coating on the reflector allows the heat to escape from the back of the lamp while directing light out the front for high output lumen brightness. Rated at up to 4000 hours, Supra Life halogens will last and average of 12 months in commercial and retail applications, while providing up to 3 years of life in normal household applications. PARs are ideal for merchandise and retail displays, accent lighting, homes, lobbies, and offices.
